Welcome to the other side :)

I've read the Harms and McDonald ``The Quick Python Book'', and O'Reilly's ``Learning Python'', but haven't been able to find python equivalents to these perl tests (lots of others in os.path, but not these :-).

if ( -x path ) # is is executable if ( -r path ) # is it readable if ( -w path ) # is it writeable

The function os.access() povides these, have a look here:

I would love to find documentation, something like ``python for the perl hacker'' that would help in the transition.

So would a lot many hackers who see the light :) ....here you go (urls may wrap):
